MAGIC SQUARE: Calculate A-B*C
The aim is to place the some numbers from the list (19, 21, 26, 27, 28, 29, 34, 50, 52, 58) into the empty squares and squares marked with A, B an C. Sum of each row and column should be equal. All the numbers of the magic square must be different. Find values for A, B, and C. Solution is A-B*C.
Find number abc
If a1c1b - 246b2 = c69ba find number abc. Multiple solutions may exist.
100% Polar bear
One afternoon in the Arctic, a father polar bear and his son polar bear were sitting in the snow. The son polar bear turned to his father and asked, "Dad, am I 100% polar bear?"
"Of course, son, you're 100% polar bear."
A few minutes pass, and the son polar bear turns to his father again and says, "Dad, tell me the truth. I can take it. Am I 100% polar bear? No brown bear or panda bear or grizzly bear?"
"Son, I'm 100% polar bear and your mother is 100% polar bear, so you're certainly 100% polar bear."
A few more minutes pass, and the son polar bear again turns to his father and says, "Dad, don't think your sparing my feelings if it's not true. I really need to know... am I really 100% polar bear?"
Distressed by this continued questioning, the father polar bear finally asked his son, "Why do you keep asking if you're 100% polar bear?"
"Because I'm freezing to death out here!"
Which is a winning combination of digits?
The computer chose a secret code (sequence of 4 digits from 1 to 6). Your goal is to find that code. Black circles indicate the number of hits on the right spot. White circles indicate the number of hits on the wrong spot.
George Ferdinand BeckerBorn 5 Jan 1847; died 20 Apr 1919 at age 72.American geologist who advanced the study of mining geology from physical, chemical, and mathematical approaches. Becker's main interest was the study of the Earth's interior, and his theoretical work on this topic was presented in a series of important papers in the 1890s; his most important theoretical contribution was Finite Homogeneous Strain, Flow, and Rupture of Rocks (1893). |
